I’ve had my HTC Evo for a couple of months or more at this point. When I first turned it on, there was an update waiting. The update installed. So far, so good.

Over the next few weeks I heard there was another update available, but it turned out there was a problem with the update. It took HTC and Sprint about a week or more to fix the problem update, but since the Evo was still in very short supply, I chose not to update it right away. What if there was a problem with the update and it bricked the phone? How would I get an immediate replacement? Better to wait.

A few days ago, Sprint and HTC started releasing the “Froyo” or “Frozen Yogurt” Android 2.2 update for the Evo. I decided it was time to take the plunge and accept the update.

There were two updates. The first one downloaded and installed, and then the second. No problems.

Now I’m asking myself, did the upgrade to Android 2.2 live up to all the hype? Android 2.2 on the Evo might be a little bit more snappy, but it’s hard to tell since the Evo already had excellent performance with the version of Android it shipped with. There are a few changes here and there that improve usability, some of them somewhat worthwhile, but was it really worth the trouble? The phone was a great device before the update. It’s a great device after the update.

Are updates to existing smartphones enough reason for consumers to get really excited over? As I see it, if lots of new basic usability and reliability can be added with a particular update, then it’s likely worthwhile. Smartphones are still evolving devices.

It seems to me that the job of adding new functionality to smartphones falls primarily to apps, and not necessarily the operating system itself. The operating system should be a stable, functional platform that offers basic functionality and services to those apps.

Once smartphone operating system design begins to mature however, the danger of updating and changing things just for the sake of change is always a potential risk. Also keep in mind that on average people replace cell phones about every 18 months, which is a much more frequent replacement cycle than desktop and laptop computers.

In the realm of desktop computer software, Microsoft Office is a great example of mature software design. There are only so many things word processing software can do. Microsoft Word and Excel both had good design and usability for me starting way back with Office 95. With subsequent releases, Microsoft seemed to sometimes arbitrarily change things just for the sake of change, which is a huge usability mistake. Computer software design is not the same as car styling design.
